William Blake and the Imagination in Ideas of Good and Evil by William Butler Yeats.

“Furious and terrible they rend the nether deep,
The deep lifts up his rugged head,
And lost in infinite hovering wings vanishes with a cry.
The fading cry is ever dying,
The living voice is ever living in its inmost joy.” [via]

Consider also:

  1. “He cried again and again that every thing that lives is holy, and that nothing is unholy except things that do not live–lethargies, and cruelties, and timidities, and that denial of imagination which is the root they grew from in old times.”
  2. “The joy of woman is the death of her beloved, Who dies for love of her, In torments of fierce jealousy and pangs of adoration. The lover’s night bears on my song, And the nine spheres rejoice beneath my powerful control.”
  3. “He was a man crying out for a mythology, and trying to make one because he could not find one to his hand.”
  4. “And he understood this so literally that certain drawings to Vala, had he carried them beyond the first faint pencillings, the first faint washes of colour, would have been a pretty scandal to his time and to our time.”
  5. “The sensations of this ‘foolish body,’ this ‘phantom of the earth and water,’ were in themselves but half-living things, ‘vegetative’ things, but passion that ‘eternal glory’ made them a part of the body of God.”
